Description:
Xtreme Spirulina Flakes are a nutritionally balanced, plant-based staple food designed to support the health, colour, and long-term wellbeing of a wide range of aquarium fish. With high levels of Spirulina algae, this formula is especially beneficial for herbivorous and omnivorous species, while still being readily accepted by most community fish.
Spirulina is widely recognised in aquaculture for its ability to support consistent growth, improved digestion, and stronger immune function. As a highly digestible ingredient, it allows fish to absorb more nutrients efficiently while helping to reduce waste output, contributing to better overall water quality.
This formula also contains natural colour-enhancing pigments, helping bring out brighter, more vibrant colours in ornamental fish. Additionally, the inclusion of stable Vitamin C and brewers yeast supports healthy fin, gill, and tissue development, making it a well-rounded option for everyday feeding.
Made using farm-grown Spirulina from the USA under strict quality controls, this food delivers reliable consistency and nutritional integrity. The flakes break apart easily in the water, allowing fish at different levels of the aquarium to feed naturally.
Xtreme Spirulina Flakes are particularly well suited to livebearers, African cichlids, silver dollars, rainbowfish, and other plant-grazing species, though they can be fed to most freshwater and marine fish as part of a balanced diet.
In our own fish room, foods from the Xtreme range have proven to be reliable staples, especially when used alongside higher protein foods to create a more balanced feeding routine.
As with many natural ingredients, the colour of the flakes may vary slightly depending on seasonal harvest conditions.
Suitable for regular daily feeding as part of a varied and balanced diet for freshwater tropical fish, particularly herbivorous and omnivorous species.

Diet & Compatibility:
Xtreme Spirulina Flakes are a plant-based staple food designed for herbivorous and omnivorous aquarium species, while still being suitable for most tropical community fish.
This formula is particularly beneficial for plant-grazing species such as livebearers, African cichlids, silver dollars, rainbowfish, and many algae-eating fish, helping support healthy digestion, consistent growth, and overall vitality.
Due to the high inclusion of spirulina algae, this food provides a rich source of natural nutrients, vitamins, and colour-enhancing pigments, helping fish maintain bright natural colouration and strong immune function.
For optimal nutrition and balance, this food pairs exceptionally well with higher protein foods such as Xtreme Community Crave Flakes and Xtreme Wrigglers®.
For a more complete feeding routine, you can also rotate in Xtreme NICE® Crumble and Xtreme NICE® Semi-Floating Pellets to provide a mix of particle sizes, feeding behaviours, and nutrient profiles.
Offering a varied diet helps mimic natural feeding behaviours and supports improved digestion, colour, and long-term fish health.

Feeding Guide:
Feed only what your fish can consume within 1-4 minutes, removing any uneaten food if necessary to maintain good water quality.
For most aquariums, feeding a small amount twice daily is the safest baseline. Many fish benefit from lighter feeding schedules, as this allows time for proper digestion and helps reduce common issues such as constipation, bloating, and internal blockages. Even for small or micro-species, skipping food for one day each week is highly recommended to help clear their digestive systems.
In our own fish room, we often stretch this further, feeding a normal portion every 2–3 days rather than daily. This works exceptionally well for large species (like cichlids or predators) that take longer to digest. However, small or micro-species (such as danios, tetras, and nano rainbowfish) have tiny stomachs and high metabolisms, meaning they generally require smaller, more frequent daily feedings with just a single fasting day per week.
Warning: Be careful when spacing out meals. Overdoing the portion size on feeding days can cause severe water pollution and bloating, creating more problems than benefits. If you are unsure, always revert to feeding a small amount twice daily (and fasting one day a week).
For fast-growing juveniles or fry, smaller portions daily may need to be offered more frequently if required, provided water quality is closely monitored.
As with all foods, adjust feeding frequency and portion size based on your fish species, tank size and filtration.

Tips Before You Buy — Food & Diet Guidance
💡 Not all fish eat the same diet - Take a moment to understand your fish’s natural feeding habits and nutritional needs before choosing a food.
🐟 Some species thrive on high protein - while others do best with a more balanced or plant-supplemented diet. Offering variety helps support digestion, colour, and long-term health.
🌿 Omnivorous fish benefit from mixed feeding - If your fish eat both plant and animal matter, consider rotating foods rather than relying on a single option.
✅ High-quality, hand-picked foods - We source brands and formulas that meet the nutritional needs of all freshwater fish.

How This Food Compares
🎯 Xtreme Spirulina Flake Formula
- 🌿 Spirulina Primary Ingredient: Formulated with premium, pure Spirulina algae as the number-one ingredient. Delivers genuine, high-potency plant-based nutrition instead of grain padding.
- 🇺🇸 USA Farm-Grown Quality: Cultivated under strict aquaculture quality controls in the United States, ensuring total consistency, freshness, and optimal raw nutritional integrity.
- 🧬 Enhanced Tissue Growth: Infused with stable Vitamin C and active brewers yeast to promote excellent fin, gill, structural tissue development, and stronger immune function.
- 💧 Highly Digestible, Clean Water: Herbivorous and omnivorous species easily absorb the premium algae cells, drastically lowering total tank waste output for better water parameters.
❌ Standard Vegetable Flakes
- 🌾 Low Algae Percentages: Treats spirulina as an afterthought, padding out the formula with cheap wheat flour or alfalfa meal while hiding behind misleading labeling.
- 🧪 Artificial Green Dyes: Relies heavily on synthetic chemical colorants to make the flake look healthy, adding zero real nutritional value while placing stress on the fish.
- 📉 Lacks Tissue Support: Missing stabilized multivitamin complexes or clean yeast extracts, frequently resulting in weaker fin structures and slower developmental progress.
- ☁️ High Organic Pollution: Indigestible grain fibers pass straight through the intestinal tract, breaking apart into a dusty film that quickly clouds water and clogs filters.
Most spirulina flakes on the market contain a small percentage of spirulina padded out with cheaper ingredients. Xtreme Spirulina Flakes lead with spirulina as the primary ingredient, which makes a meaningful difference to the nutritional value delivered per feeding. For customers keeping livebearers, guppies, and plant-grazing species, it's the most appropriate staple food we stock.
